- BALL-BEARING.

' Specification of Letters Patent.

' Application filed February 28, 1906. Serial No. 303,3 89.'

To all whom it may concern:

Be it known that I, HENRY Hnss, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Ball-Bearing, of which the following is a specification.

My invention relates to ball bearings and has for a principal object the provision of a bearing which when assembled becomes a single operative unit, and as such may be handled, shipped, and placed in working position, and in which a filling openingis entirely dispensed with. p

A further object is to construct a bearing the ball races are unbroken;

The accompanying drawing represents an exemplifying structure in which my invention is embodied.

Figure "1 is a section taken on a radial plane, and Fig. 2 an end elevation.

Reference character 1 designates an inner bearing ring provided with a ballv race '2. The outer bearing ring is divided and consists of the parts or members 3, 3 The outer bearing ring is provided with a ball race 4 formed by the juncture of race surfaces formed in the members 3, 3 of the outer ring. The juncture of the parts of the outer ring occurs at a point to one side of the tread 4 of the outer race giving an un- An outer retaining ring encircles the bearing rin members 3, 3, which it binds together an serves in some cases to strengthen. The bearing ring members 3, 3 are provided with outer conical surfaces 6 whose greatest diameter is at the point of juncture of the ringmembers and the retaining ring 5 is provided with corresponding inner conical surfaces. run in the races 2 and 4 between the bearing ring.

Owing to the shape of the race 4 and t0 the fact that no filling opening is provided, the balls 8 cannot all be readily inserted in the races in the ordinary manner. In order to assemble theg-bearing, therefore, the size 'of the outer bearing ring member 3 in relation to that of bearing ring 1 is temporarily increased, which may convenientlybe done by heating bearing member 3 and chillmg ring 1. This enlargement of the race r v a small amount of force.

Balls 8 ways is usually sufficient to permit the balls 8 to be inserted in the races by the use of a In some cases the balls may be inserted by forcewithout resorting tothe other expedients mentioned. The balls having been inserted in the races the other outer bearing ring member 3 is put in position and the. retaining ring 5,

.which has been tempor i'ily sufliclently enlarg'ed for the purpo e, by heating it, for example is placed around the parts 3, 3 of -the outeribearing ring and then contracted upon them in any suitable manner, for example, by chilling. In contracting, the conical surfaces of the rings 5, 3 and 3 serve to draw the latter very firmly together, thus insuring a proper assembled fit.

The bearing, completed as above described, forms a complete self-contained unit and as suchmay be shipped, handled and placed in working position without the possibility of accidental derangement. The entire absence of a filling opening prevents any possibility of injury which frequently occurs in ball bearings by reason of the balls striking the edges of such opening and crumbling the races or damagmg the balls or other parts of the bearing.

What I claim is:

1. In a self-contained ball bearing, the

combination of a bearing ring having a race, another bearing ring composed of two parts and having a race, the intersect-ion of the parts of said ring being to one side of the ballcontact line, and a retaining ring permanently securing the parts of the two-part ring together, the adjacent faces of the retaining ring and the two-part ring having complement-a1 gripping surfaces.

'2. In a unit-structure ball bearing, the combination of an inner bearing ring hav ng a race, an outer bearing ring composedof two parts and having a race, the intersection of the parts of said ring being to one side of the ball contact line, and a retaining ring a race, an outer bearing ring coniposed of two being provided with conical gripping surparts and having a race, the intersection of faces, and balls in the races. the parts of said ring being to one side of In testimony whereof I have affixed my the bail contact line, and a retaining rlng signature in the presence of two witnesses.
